How to Repair Black Plastic Bumpers on SUVs?
2 Answers
It depends on the extent of the damage. For minor scratches, waxing can be used for treatment. If there is a break and the broken part is still present, plastic welding can be employed for repair. Apply putty to the welded area, smooth it through sanding for aesthetic improvement, and finally complete the repair with painting. Below are the functions of the bumper: 1. From a safety perspective: It serves as a buffer during low-speed collisions, protecting the front and rear body of the car. It also provides some protection for pedestrians in accidents involving them. 2. From an appearance perspective: It has decorative value, being an important component in styling the car's exterior. 3. Aerodynamic role: The car bumper also plays a certain aerodynamic role. Additionally, to reduce injuries to passengers in side-impact collisions, door bumpers are usually installed in cars to enhance the door's impact resistance.
My car is also an SUV. Last time when the bumper got scratched, I fixed it myself. First, I thoroughly cleaned the surface with alcohol to remove dirt and grease. For shallow scratches, I used a heat gun or hair dryer to soften the plastic with hot air, then pressed it flat with a wooden stick to restore its shape. While heating, I moved the gun nozzle left and right to avoid burning. Deep scratches required plastic filler to level them out, sanding smooth after drying. Then, I applied special black plastic repair paste and finally sprayed a protectant to prevent fading. The whole process isn’t actually difficult but requires some patience. The tools can all be bought online, and the whole set costs around a hundred yuan, saving hundreds compared to going to a 4S shop.
